WATER-CLOSET.

Specification 01' Letters Patent.

Be it known that I, THoMAs' F. PAYNE, a citizen of the United States of America, residing at Pittsburgh, inthe county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Water-Closets, of whichthe following is a full, clear, and exact description, reference being had to the accompanying drawings,

which form part of this specification.

This invention relates to water closet construction and has as its object the provision of a water closet which prevents unsanitary soiling of the bowl at the front and rear portions thereof and which insures thorough flushing of the bowl.

To this end the bowl is so constructed as to avoid projecting the front and rear thereof in such manner as to render these parts susceptible of retainin unsanitary foreign deposits, and I bring a out this result without unduly enlar 'ng the bowl dimensions or otherwise ob1ect1onably affecting the symmetrical outline of the regular oval bowl, as is the case when this object of proper flushing is sought to be obtained by extendin the front and rear of the bowl andflushing rim to provide recesses or cavities at those points. While I provide points of clearance at the front and rear of the bowl, such formation does not contemplate elongation or extension of the flushing rim at the rear and undue projection of the front of the bowl. I also provide means for enabling a long sustained siphonic action with resultant thorough .fiushing action.

I will now describe my invention so that others skilled in the art to which it appertains may understand and construct the same, it, being premised, however, that changes may be made in the construction shown, which merely illustrates the preferable embodiment of my invention, without departing from my invention.

Figure 1 is a vertical sectional view of a water closet embodying my invention; and Fig. 2 is a top plan view of the same.

- In the closet shown, which is of the well known siphon jet type, 2 represents the main bodypf the bowl having the uptake or ascending leg passage 3 and downtake leg 4 of the siphonic discharge. The forward portion of the bowl is extended slightly outwardly to afford a sanitary urinal gap or space as at 5 and the flushing rim 6 extends around this PIOJGCtiOIl for flushing thereof.

At the rear of the bowl the flushing rim terminates as at 7, leaving the bowl space 8 which is flushed by the elongated aperture 9 which leads directly from the water distributing chamber 10. The water flows from the chamber 10 to the flushing rim at points 11 back of the ends of the rim. The rear of the bowl at the space 8 is preferably fiat, and the aperture or water passage 9'extends thereacross so that a wide unbroken sheet of water is caused to flow downwardly across the discharge opening 12 of the bowl durin the flushing operation. This operates or long sustained flushing action by reason of the fact that the descending sheet of water serves to seal the opening and thereby maintain siphonic action until the bowl is completely drained. By making the rear wall fiat or substantially so I obviate any tendency of the descending water to form into a broken narrow stream, as would be the case were the wall curved.

It will be seen that the closet wall at the rear is not merely extendedbut that the flushing rim terminates in such manner that a space or gap is left at the rear of the bowl. This clearance prevents unsanitary collection of any substance at the rear of the bowl and furthermore this space as well as the forward extension may be thoroughly and If an ordinary seat is used it may be so mounted on the bowl as to bring the seat opening, in advance or forward of the rear space 8 to further minimize the possibility of soiling the bowl. If desired a two piece Patented Nov. 3, 1914. A Application filed July 8, 1912. Serial no. 708,005.

or longitudinally split seat may be used in connection with my bowl. This latterform of seat is preferable as no material part of the seat projectsover the front and rear recesses. a

The advantages of my invention will be found to reside in a closet in which thor-.

ough flushing action is afforded and in which a sanitary formation of the front and rear of the bowl is obtained without sacrificing its regular symmetrical outline or reducing its flushing qualities. By terminating the flushing rim at the rear instead of only under-recessing it, I overcome the necessity of curving or recessing the bowl in such manner as to include the flushin rim and therefore increase the length 0 and otherwise radicallychange the bowl struc-- ture.

I recognize that it is old to form the bowl with a recess around which the upper face of the flushing rim extends, and I do not therefore claim such a construction, but,

What I claim and desire to secure by Letters Patent i's:

A closet bowl provided with a trap and having an inverted dam and a discharge outlet and an overhanging flushing rim extending backwardly and terminating at each side of the bowl opening, the ends of said flushing rim forming the sides of a rear recess open at the front, top and bottom, said recess being disposed between the
